The format for options is: +# +# define <name> +# default <expr> | {<expr>} | "<string>" | none +# format "<string>" +# export always | used | never +# comment "<string>" +# end +# +# where +# +# <name> is the name of the option +# <expr> is a numeric expression +# <string> is a string +# +# Either a default value or 'default none' must +# be specified for every option. An option +# specified as 'default none' will not be exported +# (i.e. will remain undefined) unless it has +# been assigned a value. +# +# Option values can be an immediate expression that +# evaluates to a numeric value, a delayed expression +# (surrounded by curley braces), or a string +# (surrounded by double quotes.) +# +# Immediate expressions are evaluated at the time an +# option is defined or set and the numeric result +# becomes the value of the option. +# +# Delayed expression are evaluated at the time the +# option is used, either in another expression or +# when being exported. +# +# String values will have the double quotes removed +# automatically. +# +# Format strings determine the print format that is +# used when exporting options. The default format +# is "%s" for strings and "%d" for numbers. +# +# Exported options generate entries in the +# Makefile.settings file.
